Mary Shirtliffe teaches Basic Magical Defense and Practical Magical Exercise at Charmbridge Academy, and administers that part of the Standardized Practical Assessment of Wizarding kNowledge. She is also in charge of the Charmbridge Dueling Club.
Shirtliffe wasn't as old as she'd first appeared, but her short, severe haircut and serious expression made her seem older. Her black leather jacket, jeans, and leather boots were incongruous at Charmbridge; she looked less like a witch than a biker. Alexandra noticed the teacher wore a pair of earrings set with blood-red stones.
